The Ultimate Nurse. Mikan is an extremely meek, paranoid, and fragile individual who suffers from hazardously low self-esteem as a result of severe abuse and bullying. This has resulted in many behavioral symptoms such as being easily intimidated, breaking down and crying with little provocation, profusely apologizing, and nervously stuttering while speaking. She constantly worries about annoying, boring, or offending others. However, as the Ultimate Nurse, Mikan tends to act much more confidently while doing her job, and she is knowledgeable. Furthermore, she sometimes gives (often unwanted) health advice to others concerning things like eating and sleeping, and may occasionally start to describe things like bodily functions in way too much detail in her wish to give the other students information on the subject at hand. Mikan is very awkward and has a warped perception of both positive and negative social interaction. When treated with any sort of individual respect or sympathy, her first response is most often outright confusion and sometimes assuming she has done something wrong.
